Fig. 12 is a plan view of a part of the bed A. showing one of the openings therethrough Within which a screw delivering disk is revolubly supported and Fig. 13 shows such a disk i side view. Fig. 14.is a side view of the screw driver and Fig. 15 shows a screw as engaged and held by the end of the screw driver. Fig. 16 shows a screw as having been actuated to final position by means of the screw driver. Fig. 17 is an end view of the not engaging means carried by the screw driver head.

Similar letters refer to similar parts throughout the several views.

In my machine I make use of three pairs of connected supporting legs,-A, A and A all connected at their upper ends to a common bed piece A The lower ends of the right hand legs A extend horizontally as seen at a, into a standard a upon the Upper end of which is pi'votally supported the yoke carrying member B. This yoke carrying member B has at its lower end a horizontal meiuher Z carrying a stud I) engaging within the hollow standard a. and held therein by means of a set. screw or bolt b as'seen in Figs. 4 and 5'. This yoke member B carries at its upper end bearings b for the shaft 8 and also a bearing for the shaft S. On that end of the shaft- S extending through the bearing therefor, is seen a pulley F, which in the case shown in the drawings is peripherally grooved to receive an actuating round driving belt 2.

adapted to be engaged by eitherone 0i the friction rolls f which are each secured against rotation upon the sleeve R which in turn is splined upon the shaft 8 but is longitudinally slidable thereon. This sleeve R has a central peripheral groove adapted to be engaged by the rollers t revolubly mounted in the ends of the clutch yoke T, which in turn is pivotally supported at its lower end on the boss I) in the yoke member B. in such a way as L0 be free to swing in a plane parallel with the axis of the shaft 3'. The compression spring T is supported from the yoke member B and operates non.

The outer face, this pulley F is rendered conical at f and 1s carrying a bevel gear 9 intcrmeshing with A link L is pivotally supported upon an ear 11 on the.yoke member B and is arranged to be actuated by means of the vertically moving rod J flexibly connected as seen, with the outer or free end of this link L, and on this link L there is revolubly supported a roller -1 whereby, by the operation of the. rod .I,.-by means ofthe lever J pivoted at'j, the link L and the roller 1 may, by engaging the cam t on the lever'T, cause such lever to occupy either the neutral positionshown in Figs. 3 and 4 or its'operative osition, to the left thereof, while when the ever, J 1' is moved to its uppermost position, the lever T is forced by the spring-'1 to the right in Figs. 3 and 4 to its operative position, for which extreme operative positions of the lever T the lever L is caused to occupy the positions indicated in Fig. 4 in dotted lines at L and L1 respectively.

Meansare provided for locking the rod in any desired position of vertical adjustment, such means prefierably comprising the notched bar J adapted to engage and hold the lever J, a spring J" normally holds 1ever J in its uppermost position.

From the foregoing description it will at once be seen that by the actuation of the clutchlcver .T the shaft .9 muy-be permitted to remain at rest. when theparts are in the relntivevpositions indicated in Fig. 3 or such shaft may hecaused to be driven in either direction according as the rightor left hand friction roll 7" is brought into engagement with the outer face f of the pulley F, whereby the flexible shaft- S connected with such shaft 8 may be driven in either direction or remain at rest as desired. This flhxible shaft s egctcnds within the screw driver, headas seenin Fig. 14. This head eonsists'oi? 'a central member C in which there is revolubly supported -the shaft V :1 similar beveigear 9 located upon a shaft V having its hearings in the extension 0 carried by the head C. On thisextension 0 there is carried, a] sleeve E secured thereon by a. screw a engaging thmugh the slot 6 in thc slecvc E, such; slotpermitting a longitudinal novpment oft-he sleeve E on the tubular extcnsip sand, a slight angular movement therconw'hcn the sleeve E is, at its extreme left hand or outermost position as seen" in Fig. 14, toand in which position it is normally driven and held by ineansof the coiled spring w, the normal torsional tendency of which operates also to so turn the sleeve E upon the tubular extension .c as'to hold the some in the position indicated in Fig. 14, that is, with the sleeve E so rotated upon the tubular extension 0 as to hold the luteral extension at the right hand end .of the slot .0 in engagement with the screw 0 whereby compression of the spring 20 in forcing the sleeve E to the position indicated in Fig. 16 is opposed by the screw 6* engaging in the notch at the end of the slot 6 and preventing the longitudinal m0vement of the sleeve E upon the extension 0. G11 the outer end 6 of the sleeve E there is threaded :1 removable split clutch u, the bore of which is such as to permit the spring of the divided ends 0 to engegeover the head of a screw m and to hold the same.

On the sleeve E are formed extensions 45 adapted to he engaged by the fingers of the operator when the member 0 is held in. using the device. The normal positions'of the parts for engaging a screw is shown in Figs. 14 and 15. After the screw has been inserted it is driven to place, by first en-= gaging-the exmnsions e nnd'slightly rotating the sleeve E, thereby permitting the sleeve E- to be drawn to the position iudicated in Fig. 16. On the extension 6 through which the shaft V extends there is secured the tubular member E which spring actuated as indicated in the same way as the member E, to normally hold the same in the position indicated in Fig. 14 and on the outer end of this member E is secured. the nut engaging clutch it having thereon the yielding jaws u the ends of which are adapted to engage within the peripheral groove on a nut such as it while the end of the shaft V carries a screw driver V bored out to receive the end of a screw such as m to permit it to cngng. the slot in the outer end of a nut such as u when in place on a screw in order to remove the nut, as it is frequently desirable to remove the nuts from the screws by operating the nuts by means of the mechanism shown at this end of the operating head of my screw driver.

In Fig. 16, the position of the parts is shown after the screw such as m has been turned to place thereby. Such screw being shown as engaging through a washer n and through a base piece N and then through a member n to be clamped thereto and having been screwed into the nut nu Refer now to Figs. 1, 2, 6, 7, 8, 9, 1t), 12

G on the right hand'end of the shaft S, tho

bearings for which are carried by the supporting standards A, A and A. On this shaft S are seen bevel gears g inlcrmcshing with bevel genre 9 carried on the lower ends of vertically arranged shafts s having elongated bearings in the cross arms (I extending transversely underneath the circular openings in the bed piece A On the upper ends of these shafts s are secured the disk heads 71. having conically formed upper surfaces. The diameter of these heads 11 is such relative to the openings therefor in the bed piece A that there is left a circular channel of a size sufficient to permit the bodies of the screws m to fall freely therein but not to receive the heads of such screws and permit them ,to fall through. The heads of the screws rest upon the upper surface. of the disk h and the upper surface of the bed piece A The conical upper surface of the head of the disk h together with the rotation of such disk and the revolving brushes is cause the screws to be forced outwardly to the slot between the head I; and the side of the opening therefor in the bed piece A as seen in plan view in Fig. 12 and from this channel the screws pass throughth slot 0 in the bed piece A a'nd thence under the spring 0 and into'the guide-sway P.comprising two plates supported at such an inclination and distance apart that the screw heads slide downarlly thereon and to the right as seen in Figs. 7 and 8 under the cap piece 77 and into the terminal and delivering portion thereof 72" comprising a slidably supported shell inclosing the lower e'ndv of the guide way P and normally held in its uppermost position as shown in Fig. 7 by means of the spring p which in turn is held in place by a Sliitable screw threaded into the connect ing member on the bottom of the'i-guide P at its outer end. The top of this; delivering mechanisnn'p has a slot extending downwardly' therein of suflicient width to receive the-body of the screws m and support the screws by their heads engaging over the top of such member 71 which is normally held by the spring 72 so as to be flush with the top of the guide P.

When the screw is to be removed from the guide way the sleeve E on the screw driver head is adjusted, to engage the screw, tip the position indicated in Fig. 14 and the clutch member '0 is forced downwardly over the head of, the screw, the spring members 'v firmly engaging the screw as indieated'in Fig. 8 with sntiicient force to hold the same as it is withdrawn from the member p and then the screw is inserted through one'of the washers n in the washer delivering disk D,.

in doing which the screw driver head with the screw m therein is operated in thematinergindicated in Fig. 9, showlng'a portlonof the washer delivering disk D and a washer n delivered thereby during which operation the screw m is forcpd through the washer as indicated and into one of the open slots (1 in the periphery of the disk D.

.Between the lower ends of the standards A and A? at the front and rear sides of the machine respec ively are secured cross bars a and a The cross bar a" serving as a support for the guides l and for the members 72 engaging over the top thereof as already described, but a sufficient-distance above the upper surface of such guides p to permit the heads of the screws m to pass thereunder.

At the lefthand end of theshatt S is seen a spur gear G meshing with a large spur gear G which latter is located on the left hand end of a shaft S having hearings in the standards A and A This shaft C has on its right hand end a bevel gear G" meshing with a bevel gear G on the inner and lower end of the short shaft :4 having a bearing in the member a extending ob; hquely downward from the bed A and carrying on its upper and. outer end the disk D which is just describedto revolve within the washer hopper D. This disk. D has open slots (Z in its periphery and is recessed around such open slots as indicated-in Figs. 2. 9 and 11. to receive the washers, and support the same. The washers are placed in the hopper l) and the rotation of the disk D engages the washers n and causes them to fall into. the recesses therefor at the slots (1 and they are carried upwardly and around by this disk I) and thus brought into a position to be readily engaged and removed by a screw m in the clutch '0 as already fully described.

, Between the standards A and A on the front side of the machine and secured thereto are seen extensions (l formed integrally with the hopper D and by which the same is supported. 3

In operating my machine a sufficient quantity of the washers 1|. are put into the hopper D to secure the proper operation of the disk D and the screws to be used are put into the hoppers H, of, which there may be any desired number and the rotation is communicated to the pul-' ley F. from any desired source of power, the operation of the lever J -coutrols the direction of the rotation of the screw driver head in the manner already described,-and the screws are forced into the. delivering mechanism p and removed therefrom by the screw driver head in the mannerindicatcd and then the screw awasher on the delivering disk D in the manner already des cribedrand such screw is then inserted in the opening therefor in the parts to be secured thereby and the screw driven to place as seen in Fig. 16 and already clearly described. I
